Stmicroelectronics L6902D013TR L6902D013TR DC-DC Switching Buck (Step Down) Regulator Adjustable 8V-36Vin 1.235V-34Vout 1Aout SOIC-8

The L6902D013TR is a complete and simple step-down Switching Regulator with adjustable current limit. Based on a voltage-mode structure it integrates a current error amplifier to have a constant voltage and constant current control. By means of an on board current sense resistor and the availability of the current sense pins (both compatible to Vcc and for Cs- compatible with GND too) a current limit programming is very simple and accurate (±5%). Moreover constant current control can be used to charge NiMH and NiCd batteries. The device can be used as a standard DC/DC converter with adjustable current limit (set by using the external sense resistor). The internal robust P-channel DMOS transistor with a typical of 250mR assures high efficiency and a minimum dropout even at high output current level. The internal limiting current (latched function) of typical value of 2.5A protects the device from accidental output short-circuit avoiding dangerous loads damage.
